The text summarizes the basic knowledge about the functioning of the soil ecosystem with a focus on soil protists and dominant groups of soil animals. Characteristics of each soil animal group include basic morphology, ecology, distribution, population dynamics and their importance in the soil ecosystem. The aim of the text is to gain a basic understanding of the diversity and interactions of soil fauna with the soil environment. It deals with the ecological classification of soil fauna on the basis of body size, presence in the soil during the life cycle, food preference and by locomotion. It highlights important morphological and ecophysiological adaptations of soil fauna to physical and chemical environmental factors. The text also gives an overview of the basic methods in the field collection of soil fauna and their extraction from soil samples under laboratory conditions. It further informs on the method of taxonomic identification and ecological evaluation of soil fauna communities. Discusses the soil fauna of different types of ecosystems. It highlights the differences in soil fauna communities that inhabit grassland and forest habitats, and agricultural soils. This teaching material is intended for students in biology degree programmes.

Crystallography deals with discerning the arrangement and bonding of atoms in crystalline solids. Almost immediately after their discovery, X-rays began to be used to study the internal structure of substances.

The first chapter of this textbook deals with the basic concepts of crystallography. At the beginning, crystalline solids are characterized. In the next section, the basic types of bonds and their characteristics are briefly presented. The main subject of this chapter is the interpretation of basic concepts such as symmetry operations, translational periodicity, grid, elementary cell. Spatial lattices and crystal systems are presented. At the end of this chapter, attention is paid to the description of individual types of defects in crystal structures. In the second chapter, the Bohr model of the hydrogen atom is presented. Individual quantum numbers and their meaning are given.

Next, energy levels and allowed transitions within an atom with multiple electrons are described. The second chapter concludes with the characterization of the basic absorption and emission processes. The third chapter is devoted to the production of X-ray radiation and its properties. Sources of X-ray radiation and a description of their operation are presented.

Interaction of X-ray radiation with matter, absorption and detection of X-ray radiation are the subject of the last part of this chapter.

Cieľom tejto knihy je spracovať názvoslovné zásady a pravidlá, podľa ktorých sa tvoria slovenské názvy biochemických zlúčenín. Táto monografia je po dlhšom čase prvým pokusom o spracovanie tohto problému, a preto dúfame, že bude pomôckou a prínosom nielen pre študentov a učiteľov ale aj vedeckých pracovníkov. Poslúži aj študentom stredných škôl, ktorí majú záujem o biochémiu a molekulovú biológiu. Kniha obsahuje najnovšie názvoslovie, zásady a pravidlá pri tvorbe názvov biochemických zlúčenín. Kniha plne aplikuje odporúčania spoločnej komisie Medzinárodnej únie pre teoretickú a aplikovanú chémiu (IUPAC) a Medzinárodnej únie pre biochémiu a molekulárnu biológiu (IUBMB) so zahrnutím aktuálnych úprav názvoslovia, stereochémie a grafického znázornenia štruktúr podľa IUPAC.
